To @ZZ 'Inkom 5' may Concern.

lle it known that we, Enorm F. HATHAq wax and Cirxnnns linx. bothcitizens of the United States. and residing. respectivel)'q atDorchester and Boston, both in the county7 ot Sntloll; and State otMassachusetts, have invented an ifinpro.'ement in Machines forSeparating' and Selecting' lYarp-Threads or the like. which thefollowing description7 in connectr 'in with the accompanvim drawings, isa specitication, like lettere on the drawings representine' like parts.

This invention relates to textile machines and more p rticularly tomachines for operating upon warp threads preparatort'v7 to theirinstallation in the loom, such class of machines comprehending` warpdrawing, warp tying, ceinenting and twistingv machines. as well as othermachines requiring the coordinate separation and selection ot suchsuccessivo members ot one or more series ot loom elements7 such, forexample, as the eres ot one or more harnesses cordinatelv with the'threads ot a new warp and the dents ot a loom reed.

llvhile .our invention is applicable to textile machines other thanthose above recited, it has particular application to such machies andator illustrative purposes, we have shown one. emhodiment thereof appliedto a machine .tor drawing in warp thread lirouejh the heddle ot aplurality harnesses and the dents ot' a loom reed. it will loeunderstood that such einliodinient' ot' our invention is illustrativeonly ainY hat the same as to certain ot its 'features may have extensivapplication to other iorins of warp drawing machines than the specificone herein shown. as well as to textile machines other thanthose used'for the specific purpose of drawing' in warp thread".

E i L L Uur invention will he liest understood hv reference to thefollowing description when taken in connor-tion with the accoinpanvinnjot one specific embodiment le its si pe will he more paro it in theappended In the drawings: Figure shows inI plan and pa tially brokenawa7 the principal working parts ot' a warp drawing machine embodyingone torni of our invention; Fig. '2 shows one end ot the machine in rearelevation; Fig. 3 is a similar view ot the mid portion ot the machine;Fig. l a detail in sectional elevation showing' the support for thelower reed liar; Fie: 5 is'a view similar to Fig. f5 hut showing' tnenext adjacent por- Y `tion in elevation showing the clamp actuatinglever; Fig. l2 is a detail in plan showing' the connection ot the leverto the plate; Fig. 13 is a detail in enlarged section. showing the latchfor the auxiliary head; Fig. ll a detail in elevation showing` the stopblock for the auxiliarY head; and Fig. l5 is an end View oi the.coupling for the sepa 'ating shafts.

Referring to the drawings, we have there shown for illustrativepurposesone i'orni of our invention einhodied in a well-known torni otwarp-drawing machine, the specitic machine shown being intended moreparticularly for use in conjunction with warps of extra width or extent.

ln the illustrated machine there is provided a bed or frame work l, uponwhich are appropriately positioned the various loom elements, such asthe warp threads (see Figi. l) harnesses P) (Fig. and reed l. These aresustained herein parallel with the length of the machine and so relatedto the separating', selecting and V'threading' mechanisms that relativetraversingy movement is provided between the latter and the severahsetsof loom elements.

dlhilm lor this purpose, it desired, the

separating mechanismsl v20 5 'and caused to Warp, harness and reedsupports might themselves be movable past the threading and selectingmechanism and the latter held fixed, in the present case the variousseparating and selecting devices are sustained upona carriage 5, whichis mounted 'to be moved lengthwise the bed 1 by means of the lead screw6, thereby to move operatively across and traverse the loom elements,

which latter are ygiven a relatively lsmall compensating movement only.During the traverse of the carriage, suitable threading mechanism, suchas the Warp-drawing needle 7, having suitable reciprocating drivingmechanism, is caused to draw successive Warp threads through theselected harness eyes and Ireed dents.

In the present machine the'selecting and for `the warp threads, harnesseyes and reed dents are also supported upon the traversing carriage movetherewith lengthwise the machine. While any suitable selecting andseparating devices may be employed, in the present instance we haveshown a machine fitted with awarp separating worm or screw 8 of thegeneral type shown in British Patent No. 4661 of 1904, harnessseparating worm of the type shown in U. S. Patent No. 600,670, and areed opener 10'0 ,fthe general typeshown in U.' S. Pat-- 'ent)ol-*871,680 y In' the present machine also, as in thev machines of theAsaid prior patents such .separa-ting and selecting devices are providedwith longitudinally extending actuatingv members, herein comprising theshaft 11 for the warp Worm 8, the shafts 12 (herein four innumber) forthe harness worms 9, and the reed opener shaft 13 for the reed opener10. `These longitudinally extending actuating shafts receive journalsupport at lor adjacent their active ends, the reed shaft `in a'bracket14 mounted on the carriage 5, and.

the remaining shafts in an extension arm 15, also supported by the saidcarriage and movable therewith. To support as well as drive these shaftsat their opposite ends there is provided a'second traversing 'carriage16 cari-ying a head 1 7 endsof the shaft receive ]ournal slipport andasecond hea'd 18, the' latter associated :tvith pattern controlmechanism, such as the lfpattern chain 19 and appropriate clutches y[20interposed between the pattern chain and the driving mechanism, wherebyany of thev several operating shafts for the selecting mechanism may beactuated and timed in -accordance with a predetermined pattern 6,arrangement to effect the separation and presentation to the needle ofthe warp threads, harness eyes and reed dents in appropriate order andat appropriate times.

The pattern control mechanism as shown, being well known upon machinesof this i come excessive,

` the advance of the onl which the I class, (disclosed for example as toits main features in the said with the constructional arating mechanismand drawingin mechamsm across the full extent 'of threads, harnesses andreed.

the warp 1f the capacity of the machine is increased y to permit it todraw' extra wide warps, the length of the actuating shafts is apt utobeleaving a long overhand between their supports at the carriage 5 andat the pattern carriage 16. To meet this difficulty, we have hereinprovided an inter- British Patent No. 4661. of 1901) and our inventionnot being par` ticularly concerned .details tliereof,no furtherdescription of its mediate'supporting carriage 22 also slidably mounted'upon the frame and 'carrying the hea-d 23 which affords for the harnessreed` and the warp. l i

WVhen the machine is to be used for wide work which-in practice Vmay runfrom five to an intermediate jour-m .nal support for the severalseparator rods,-

eight feet in extent, the actuating shafts 11 and ..12 are preferablyprovided of an un- `broken length extending Ifrom the supporting arm 15of the carriage 5to the head 17-` on the Carriage 16 A ,-the'intermediate head 23 providing merely a plain j oui-nal support for therods. This condition is represented in Fig. 6, which shows the warpworin shaft 11 extending through the auxiliary head 23 and .journaledtherein. In operating the machine under these conditions, the drawinginoperation is commenced with the carriages 5 and 1.6 at their startingpositions and the carriage 22 closely adjacent thevcar-v riage 16. Asthel drawing-in operation progresses thetraversingcarriage and thepattern head carriage gradually move tothe f left (as viewed in 1"ig.1),leaving the then ioe stationary intermediate carriage 22 behind.

This movement is preferably continued until actua-ting shafts relativelyto the head 23 brings tle rods at the position which affordsthedesiredsupport, whereupon the 4intermediate carriage then and thereafteris caused to be moved and advanced also with the traversing carriage 5..This may be effected by any desired means, but herein we have .providedupon the gib 21 (see ["ig. 14) the stop block 24 to which is secured theplate 25 to slide upon the upper face of the giiileway afforded bvadjacent machine frame, the said block the near side of' theintermediate cai'i'iage22, when it desired to fiiiove the latter withthe pattern-head carriage. Obviouslythe block 24 may beadjusted 'tovarious positions lengthwise the gib so that the final positionoverlying and adapted Liedes? @5 of the intermediate carriage relativelYto the pattern-head Carriage may he selected at will and to secure thenost favor: ble position for the intermediate carriage dependent on thelength ot` actuatingw shafts einploved.

it will. therefore, he seen that, in the use ot' this machine with extrawide warps. the patterndiead carriage is preterablv started in closeproximity to the internualiate carriage and then, after withd 'awingtrom the intermediate carriage for a space dependent on the location otthe block 2l, is caused to continue its movement with the intermediatecarriage also moved therewith.

ln order that the described machine may he employed either with extrawide warps or with warps olf ordinariv widtln provision is preterahlvmade wherehv the relatively short separator rods, which are customarilyused with work ot the latter class, can he employed in co'uiectimi withthe auxiliar;Y head.I and tlj'e len; h ot the traversing` unitcorrespondinni;Y reduced. For this purpose pro-- vision i mai e torreceivingr the ends ot such short rods i the intermediate carriage asthey wouid )e received in the head 1T and 'for conjhney them thereat tothe patternhead shcr z iliary shafts 2t. ri`his is the conditioiArepresented in i and T where the ends ot the rod llA are shown entringga sochet torined in the coupling' 2T, which socket provided with thehinged liey 2S adapted to enter a iff) in the end ot the rod. The lievis provided with a latch I3() engagingA a shoulder in the rod and isnormally pressed into engagement therewith by iA l.

Ia spring El, sothat the rod7 when inserted in the socket, will he heldlocked therein, but can he ren'ioved theretroin b v pri,,.,meout thelatch,

The ausiliariy rod LH? which extends to a Corresponding ctnipling on theh ad ii is preterablvV lixedlv secured to a collar 32, which shutsinjainst the head ot the coupling yThe colar l2 is provided with one ormore pins S39 therein two) lifted in and extending trom its abutting'tace and registen ing with n'ienihers of a series ot corresponding holesin the abutting v ol` the coupling. ller-cin (see itin: l5) twelve suchholes are employed.

ing the said screw 34 and withdr: wing the coupling' the latter with itsseparator shaft can be turned one-twe tth ot a revolution or an)Ymultiple thereof and then replaced.

in the described form of machine, when the machine is employed with theshort separator shafts and the auxiliary shafts, as described, theintermediate carriage is preferably'secured at a lined distance tromlthe pattern-hezul carriage lt and travels therewith at all times as thelatter with the traversing carriage moves during the warpdrawingoperation. For this purpose any suitable means tor thus locating theintermediate carriage relativelyY to the patternhead carriage may beemployed7 but in the described einbodiinent ot our invention we haveprovided tsee- Figs. l and lli) one or more spring-pressed latch bolts35 ver-ticall'v arranged near the edge ot the carriage 22 and adaptedr`when located at the required distance from the pattern-hard carriage, toregister with and enter a hole formed in the gil) 2l connecting` thecarriages and it. The. bolt S5 is provided with a head 3o by which itcan be withdrawn and it also has a laterally extending pin 1ST working'in a vertical slot 3S so that when raised with the pin 37 above theupper surface ot' the carriage the bolt can be turned and the pin 3Twill hold it against rentrance. The :arriag'e 22 therefore can ne eitherlocked to the pattern carriage t'or use. with the short actuating`shafts or treed therefrom and employed with the long shatts aspreviously described.

In warp-drawing machines it is cnstonr ar)7 to support the reed uponsome movable carrier to plrmit ot' longitudinal adjustment during;n theope `ation ot the machine in response to the action of the reed openeror other reed iliositioifiingry device. This has ordinarilyV beenaccomplished bv providing a reed carriage ot' suhstantiallj/vTrectangular formation adapted to hold the reed rigidly against vibratorymovement as a whole, while permittiimr the entire carriage to have anadj ustine' longitudinal movement. 'While this provides a solid supportfor the reed, the parts undereoine,` movement are neeessai-ily heavyYand impose considerable work upon the reed opener yand the reed splits.

This is espec-hill)Y the ease where warps ot' eX- l l th lOl) ' to 5and`8 to 12, the reed 4 is sustained at l clamps 39 which depend fromthe carrier,

suitably selected vpoints in its length by bar 40, the latter in turnbeing sustained by a plurality of hangers 41, provided each with aroller 42 tracking upon the stationary reed bar or track 43. The latteris held against transverse displacement in vertical guides 44, but maybe vertically adjusted by means of end adjusting rods 45. and anintermediate adjusting rod 46, all of which have threaded engagementwith the supporting bar 43, so that, when the rods are turned, thelatter is raised or lowered.

In'the present instance we have provided means for simultaneouslyturning, not only the end adjusting rods 45, but also the intermediaterod 46, so that the reed bar 43 can. be adjusted by the operator fromone end of the machine. ln the present instance 1 this is ei'ected byproviding one'ot' theieILd knurled hand wheel 47 by which the same Vmaybe turned, this acting, througlrthe bev-j eled gearing 48 near the topthereof, t'o turn the horizotnal shaft 49 suitably journaled near thetopof the machine framing. The shaft 49, in turn connects with theintermediate adjusting rod 46 by means of beveled gearing 50 and withthe remaining end adjusting rod 45 by means of beveled gearing 5l, sothat, as the hand wheel 47 turns, all three adjusting rods are given asimilar and corresponding.adjusting movement effecting a uniform raisingor lowering of the reed bar and reed.

j While support may be provided for the lower bar of the reed throughoutall or a Vlarge portion of its length, in the present instance we haveprovided supporting means for a portion of its length only, and havealso lprovided such supporting means upon the Itraversing carriage.5,-wherebyvit affords supporttothe recdffafctja'llilent the line of needleaction and.where "mostgneded inthe present machine this is' .'ttained byprovidingfa channelfliheftauppoifti (see Figs.

` l, 3 and 4) :12in which .fthe re'exl vbar can transverse movement.

no reed supp. rtng devices are; lrequired for the reed on the reedcarrier other than they clamps 39. j l j,

Referring to Fig. 9, each-reed clamp is provided with jaws 53 and 54which tightly grip the upper bar of the reed.

Thereleasing bar extends the entire length of the carrierbar 40' and isoperatively related to all the clamps as above described, so thatv whenmoved longitudinally, it simultaneously opens all the clamping jaws andreleases the reed. .,l, j .1 Means are preferably providfftdr /mov-j ingthe releasing bar from somefg'l en point`,/ and for this purpose thereis preferably ro-y vided "(see.1`igs. 3, 11 and 12) a hand "l ver 62which is pivotally mounted to engage a notch 63 in the edge of thereleasing bar 59, so that, by movement of the lever yabout its pivot,the bar may be movedsimulta'peously to.l open the clamps. lfVhile thel/ever '62 ay edge 61, so that, -Y
